SASH

SPECIFICATION forming part of'Letters Application filed March 18, 1886.

To all whom it may concern.-

Be it known thatI, EDWIN R. FERRY, of the city of New Haven, county of New Haven,

State of Connecticut, have invented new and Improved'Sash-Loeks, of which the following is a full, clear, and exact description.

This invention consists in a novel device for drawing the rails of the upper and lower sash of a window together to exclude the cold and dust, and to lock them together so that neither sash can be moved until released by the look from the interior, as will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a view in perspective of my improved sash-lock secured to the upper and lower rails of windowsash, and in position to permit either sash to be raised or lowered or to be locked together, as required. Fig. 2 represents a plan top view of my sashlock, also secured to the dividingrails of the upper and lower sash of a window, showing the two rails drawn snugly together and locked, so that neither sash can be moved until unlocked from the interior. Fig. 3 represents a longitudinal sectional elevation of this lock secured to the upper and lower rails of window-sash, the sash being also shown in section, and the dotted lines represent the fastener unlocked, the same as in Fig. 1, to permit the sash to be raised orlowered without inter-- fering with the lock; and Fig. 4 shows a modification of the locking-stud.

A A in the accompanying drawings represent the dividing-rails in the upper and lower sash of a window. This lock is secured to the upper sides of thesetwo dividing-rails A A by screws, in the usual manner.

On the dividing-rail A of the upper sash is secured a plate, B, having a notched stud, J, projecting therefrom, as represented in the several figures.

On the upper dividing-rail, A, of the inner and lower sash is secured a plate, E, upon which is mounted a locking-lever, D, carrying a latchbar, 0, by which the rails of the two sashes are drawn snugly together and locked. This latching and locking part consists of a plate, E, secured to the upper side of the dividingrail A of the lower sash, from which extend two ears or sides,.F F. To these sides F is Loo K.

pivoted a locking-lever, D, which is provided on its two sides with eccentrics G G, as shown in Fig. 3. To these eccentrics G G is fitted the latch-bar C, having a cross-bar, I, which passes over and is drawn beneath the notched end J of the stud on the plate B by the eccentries G G onthe locking lever D when the lever is turned inward so asto rest upon the inneredge of the plate F, as represented in Figs. 2 and 3.

The operation of this sash lock may be briefly described as follows: To draw together the dividing-rails of the two sashes, the latch-bar C and locking-lever D are placed in position, as represented in Fig. 1. The locking-bar D is then turned inward, by which operation the cross-bar I of the latch is drawn beneath the hooked end J of the stud on the plate B, drawing the two rails together, closing the space between them, and locking them firmly together, as shown in Figs. 2 and 3. 7

To unlock the rails of the two sashes, the

"locking-leverD is turned to the position shown in Fig. l and in dotted lines, Fig. 3, when either or both sashes may be raised and lowered at pleasure without interfering with the look.

It is quite evident that instead of the eccentrics G G, to move the latch-bar back and forth to engage and disengage with the hook J, crankpins may be substituted therefor which would accomplish the same movements as the eccentrics.

the notched end J of the stud on plateB is provided with two notches, so that in case the meeting-rails do not align the latch-bolt C will be sure to engage the stud.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent- 7 The fastener herein described, the same consisting of the attaching-plate, the lever D, pivoted at its forward end to the attaching plate, and having the eccentrics G G on the opposite sides of its forward end, the latchbar C, having the inner ends of its arms journaled on the eccentrics, and the cross-bar I, connecting the forward ends of said arms and the catch or hook J, substantially as set forth.
